Meteorologists typically examine atmospheric soundings in the course of preparing a weather forecast. The skew-T / log-P diagram provides the preferred method for analyzing these soundings. This module comprehensively examines the use of the skew-T diagram. It explores thermodynamic properties, convective parameters, stability assessment, and several forecast applications. The module is designed for both instruction and reference. It also comes with an interactive Web-based skew-T diagram that calculates several common forecast parameters.

Great module! The only thing I would change is to make the skew-T diagram questions more user friendly when figuring out LCL, LFC, etc....would be nice if we could "mouse over" the skew-T and it would have a selection bar for choosing parallel lines for each parameter (Saturation Mixing Ratio, temperature, dry adiabats, etc).

chibosh 2018-09-09 22:21:13

Take lots of notes during the exercises. The different values run together after a while. Also, the skew-t diagrams are hard to read.

clane 2018-09-09 17:45:12

I think adding videos would make things easier to understand. The whole thing was also quite long, which makes it hard to focus

Estara este curso en español? Gracias.

SRJarvis4472 2018-06-11 07:54:24

This course was very useful to my studie and it helped to enhance my knowledge further o the subject of Skew-Ts

KelliGrey 2018-04-19 16:57:09

The lesson was very thorough and helped me gain a much better understanding of what Skew T charts are, how to read them, and how to apply them to forecasting.

alkello 2018-03-04 14:45:13

I felt like the lesson was too long. I think it should be broken up into sections and those individual sections should each have their own graded quizzes. That way its easier to access what specific topic you need to review.

Yabbles 2018-03-01 11:45:31

I did this for a grade.

alimoges 2018-02-01 09:35:13

It is entirely too difficult to calculate certain elements of a Skew-T on a computer screen

todayweather 2017-12-14 15:45:10

the skew-t it's from the most important tools to determined the upper air condition and make more accurate forecasting, my predict get more better after using skew-t diagram.the NWP and skew-t diagram together gives more precious information.

Skeeterroo2 2017-12-03 18:02:03

Some of the skew-T were difficult to see well when answering questions. This made accurate answers hard to achieve.

amadeu120 2017-11-28 18:31:18

The questions were a bit challenging however they did wonders for learning about the material.

gcutt 2017-11-26 13:16:10

Extremely long and extensive, poor quality in many images for questions and exercises

MelPetty 2017-10-29 16:35:09

It was entirely too long. It should not take over 8hrs to complete a comet module and that was me giving up early.

jlsbaltazar 2017-10-05 09:03:02

The skew-t lines are small, blurry, and difficult to read on a computer screen. Not being able to draw on the charts also makes this difficult for someone without extensive practice.

Hello

cclarkro1 2017-07-03 07:14:28

The weakest portion of this lesson and the associated quiz are the graphics, which are usually too small to adequately examine and become somewhat pixelated when using the zoom feature on a browser. The size of interactive Skew-T helped during the lesson, but perhaps there should be something of similar size on the quiz.

MehlingM 2017-06-24 06:43:38

Some of the quiz questions did not seem to be straight forward.

SCHUM 2017-06-18 06:44:17

The charts are a little hard to see especially when having to determine intersecting points.

Ahickey77 2017-04-26 01:20:57

It was a great lesson but the skew t's provided were hard to read

uaejaw 2017-04-06 15:46:00

thanks found it helpfull

I am a veteran forecaster of 27 years in the National Weather Service and have still managed to learn a lot from this course. It was an excellent review.

mgree090 2017-02-14 08:13:05

great!

JudyHinch 2017-02-13 12:47:36

hard

GAYLER 2017-02-05 21:58:08

Show how to read the Skew-T and show how to calculate for video and animation would have been more help than just reading dry material.

ASCI517Course 2017-01-29 15:46:35

Good Lab

esigala 2017-01-28 21:38:37

There is waaaaaaay too much information here for it to be processed and retained. There are so many different topics and sections of reading the Skew-T that it is difficult to keep up. Further, the tiny images used make it difficult to select the correct information/data.

mahughson 2017-01-22 15:41:34

the amount of information presented and expected to be mastered in such a short time is impossible. It may have been helpful to have actual examples of what the weather is visibly doing while looking at the Skew-T diagrams.

katturner92 2017-01-03 21:18:23

Great to cement to knowledge I already had, covers all things aerological!

NordeenJ93 2016-12-05 03:45:24

It wasn't a bad lesson, just extremely long. Took longer than I thought it would and also kind of bland. Some areas needed more images and simulations, while other areas were just fine.

t3hite 2016-11-15 17:04:54

This lesson took me much longer than the estimated time. I think 10-12 hours would be a better estimate.

TVGuy321 2016-11-01 22:15:19

The information is great, but it's so much that it's like trying to drink from a fire hose!

pidermal 2016-11-01 13:57:19

Definitely not easy

Seagull74 2016-11-01 12:25:57

A+++

shanna.stocks 2016-10-31 22:46:23

Thank you. I enjoyed the interactive learning and hope to return to the module for revision in the future.

Stormy71 2016-10-30 20:11:33

Module is too long. Took me 16 hours to get through it. Information overload.

Mooregran12 2016-10-27 20:49:26

This is too long for the attention span of most pupils

TimRossman 2016-10-26 13:14:50

Great resource!

dkimonye 2016-10-25 04:01:35

It is quite educative and very beneficial to the forecasters

This is a long but comprehensive module. I found it to be very useful.

Lwaltlpn 2016-10-16 17:11:43

Overall this was a great learning format. Some of the Skew-T's that were depicted could be improved. Lines were difficult to distinguish on just a couple.

Alex1305 2016-09-28 16:32:39

A fantastic learning resource for all who want to understand how Skew Ts can be used to help make forecast on a range of different weather.

JoeDeLizio 2016-09-23 15:54:29

Awesome module here. A Rutgers student in atmospheric thermodynamics and this really helped me learn a lot. The forecasting section was really cool, felt like I got my feet wet with actual forecasting and the tips you guys gave were great. I really enjoyed this whole lesson, I learned a great deal more about my passion. I will be visiting here again to learn more.

BustingBravo 2016-06-14 14:51:14

Great.

sparling 2016-03-14 17:04:57

Very clear explanations, an excellent resource for educators.

matthewblittle 2013-09-19 02:10:46

I began with little understanding of skew-T analysis and this module brought me to a much better understanding. However, expect to spend more than 8 hours if you have little skew-T background but want to learn from the module.

davrusso 2013-08-31 05:19:39

Comprehensive and highly educational. Soundings graphics are often difficult to read due to size and/or quality. Paste them into a graphics program and print full-size, to get the most out of this course.

The goal of this module is to teach the novice forecaster to effectively use the skew-T/log-P diagram. After completing the module, they should be able to read and interpret a sounding plotted on a skew-T/log P diagram and apply that information to a weather forecast.

Performance Objectives

Given a skew-T/log-P diagram, identify and describe the various lines.

Given a sounding plotted on a skew-T/log-P diagram:

Read or calculate the thermodynamic properties at various levels.

Determine the convective levels, including the LCL, CCL, LFC, MCL, EL, and MPL.

Determine stability indices such as LI, SSI, KI, TT, and SWEAT and use them to assess the potential for severe weather.

Describe how CAPE and CIN are determined.

List and describe the different types of stability and identify them in a sounding plotted on a skew-T diagram

List and describe the different types of lapse rates and relate them to stability.

List and describe processes that alter stability and give examples of common cases where those processes occur.

Given a suitable synoptic environment and a sounding plotted on a skew-T/log-P diagram, interpret the sounding with regard to common forecast problems.
